{"id":"UBUNTU-CVE-2023-1255","details":"Issue summary: The AES-XTS cipher decryption implementation for 64 bit ARM platform contains a bug that could cause it to read past the input buffer, leading to a crash. Impact summary: Applications that use the AES-XTS algorithm on the 64 bit ARM platform can crash in rare circumstances. The AES-XTS algorithm is usually used for disk encryption. The AES-XTS cipher decryption implementation for 64 bit ARM platform will read past the end of the ciphertext buffer if the ciphertext size is 4 mod 5 in 16 byte blocks, e.g. 144 bytes or 1024 bytes. If the memory after the ciphertext buffer is unmapped, this will trigger a crash which results in a denial of service. If an attacker can control the size and location of the ciphertext buffer being decrypted by an application using AES-XTS on 64 bit ARM, the application is affected. This is fairly unlikely making this issue a Low severity one.","modified":"2026-01-30T01:16:06.569475Z","published":"2023-04-20T17:15:00Z","related":["USN-6119-1"],"upstream":["CVE-2023-1255"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-1255"},{"type":"REPORT","url":"https://www.openssl.org/news/secadv/20230420.txt"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6119-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-1255"}],"affected":[{"package":{"name":"openssl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/openssl@3.0.2-0ubuntu1.10?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.2-0ubuntu1.10"}]}],"versions":["1.1.1l-1ubuntu1","3.0.0-1ubuntu1","3.0.1-0ubuntu1","3.0.2-0ubuntu1","3.0.2-0ubuntu1.1","3.0.2-0ubuntu1.2","3.0.2-0ubuntu1.4","3.0.2-0ubuntu1.5","3.0.2-0ubuntu1.6","3.0.2-0ubuntu1.7","3.0.2-0ubuntu1.8","3.0.2-0ubuntu1.9"],"ecosystem_specific":{"binaries":[{"binary_name":"libssl-dev","binary_version":"3.0.2-0ubuntu1.10"},{"binary_name":"libssl3","binary_version":"3.0.2-0ubuntu1.10"},{"binary_name":"openssl","binary_version":"3.0.2-0ubuntu1.10"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-1255.json"}},{"package":{"name":"nodejs","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/nodejs@12.22.9~dfsg-1ubuntu3.6+esm2?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["12.22.5~dfsg-5ubuntu1","12.22.7~dfsg-2ubuntu1","12.22.7~dfsg-2ubuntu3","12.22.9~dfsg-1ubuntu2","12.22.9~dfsg-1ubuntu3","12.22.9~dfsg-1ubuntu3.1","12.22.9~dfsg-1ubuntu3.2","12.22.9~dfsg-1ubuntu3.3","12.22.9~dfsg-1ubuntu3.4","12.22.9~dfsg-1ubuntu3.5","12.22.9~dfsg-1ubuntu3.6","12.22.9~dfsg-1ubuntu3.6+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"libnode-dev","binary_version":"12.22.9~dfsg-1ubuntu3.6+esm2"},{"binary_name":"libnode72","binary_version":"12.22.9~dfsg-1ubuntu3.6+esm2"},{"binary_name":"nodejs","binary_version":"12.22.9~dfsg-1ubuntu3.6+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-1255.json"}},{"package":{"name":"openssl","ecosystem":"Ubuntu:Pro:FIPS-preview:22.04:LTS","purl":"pkg:deb/ubuntu/openssl@3.0.2-0ubuntu1.10+Fips1?arch=source&distro=fips-preview/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.2-0ubuntu1.10+Fips1"}]}],"ecosystem_specific":{"binaries":[{"binary_name":"libssl-dev","binary_version":"3.0.2-0ubuntu1.10+Fips1"},{"binary_name":"libssl3","binary_version":"3.0.2-0ubuntu1.10+Fips1"},{"binary_name":"openssl","binary_version":"3.0.2-0ubuntu1.10+Fips1"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-1255.json"}},{"package":{"name":"openssl","ecosystem":"Ubuntu:Pro:FIPS-updates:22.04:LTS","purl":"pkg:deb/ubuntu/openssl@3.0.2-0ubuntu1.10+Fips1?arch=source&distro=fips-updates/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.2-0ubuntu1.10+Fips1"}]}],"ecosystem_specific":{"binaries":[{"binary_name":"libssl-dev","binary_version":"3.0.2-0ubuntu1.10+Fips1"},{"binary_name":"libssl3","binary_version":"3.0.2-0ubuntu1.10+Fips1"},{"binary_name":"openssl","binary_version":"3.0.2-0ubuntu1.10+Fips1"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-1255.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"low"}]}
